A bent rear axle could cause this.
With the car in neutral and jacked up and supported, turn the wheel and feel for the brakes dragging (the tire will speed up and slow down as it moves from the dragging area to the non-dragging area).
You make have to remove the tire to really get a good idea of whats' going on.
Question: how are you 100% sure it is the rear?
